Abstract

To provide a battery protecting circuit in which a delay circuit for generating delay times for a plurality of abnormality detecting functions is realized without increasing a circuit scale. A control circuit of a battery protecting circuit is provided with a function of, when an abnormality requiring a short delay time is detected while a delay time is counted, resetting count of the delay time for the detected abnormality.
